it's a rep challenge so I wouldn't be fussed.
But if you were to reset each rep like your first, you wouldn't be forward of the bar and your lower back would not round as much (which I'm more worried about)
Your first rep was a deadlift, then the rest were much close to a stiff legged deadlift.
but you wouldn't have got as many reps.
Watch it again and judge by the position of your lower back against the line in the wall.
you start higher and higher each rep..
If you felt tight then all good.
Top effort and so far, you are the winner....
